Abstract (en)

[origin: US2005121646A1] The antifreeze of the present invention is including propylene glycol, first material, and second material. The first material is normal aliphatic dicarboxylic acid in which number of carbon atoms is from 10 to 12, salt of the normal aliphatic dicarboxylic acid, or mixture thereof. The second material is benzimidazole compound which has a benzimidazole skeleton, salt of the benzimidazole compound, triazine compound which has a triazine skeleton and has a mercapto group, salt of the triazine compound, or mixture thereof. Such antifreeze has less environment load than antifreeze including ethylene glycol. Furthermore, such antifreeze does not cause metal to corrode more than the antifreeze including ethylene glycol.
